Unfortunately, I have two situations where that isn't true.

For the first, I wish that just loading the PPS drivers enabled the
PPS_SYNC option in the kernel, but it doesn't seem to. (if there is
a way to enable 'option PPS_SYNC' with a generic kernel I'd like to know,
but my experients didn't lead me that working. I still have to compile
the kernel for my GPS connected NTP servers. Which makes me wonder why
the PPS drivers are a kernel loadable object. 

The second is that the username handling is still limited to 32-bytes,
which really cramps my logins for 'billyjoebobuser at somesillydomainname.com'
so I have to build a custom kernel with longer usernames patched for
the systems that need to deal with system logins like that.
